Targeted Arsenic and Uranium Public Health Study
A Biomonitoring New Hampshire Project Biomonitoring New Hampshire logo
We come in contact with chemicals every day. They are in the food we eat, the air we breathe, and the objects that surround us. The question is—How much of those chemicals is actually getting inside our bodies? Are those chemicals causing disease or are they not harmful to us?



We need your help to answer these questions!


We are conducting a targeted public health study looking at the relationship between two chemicals that might be in your well water, arsenic and uranium, and whether those chemicals are getting into your body. We will do this by testing the water from your home and your urine.

How long will it take?

Less than 2 hours of your time over the course of a few days. This includes the time you will spend with study staff during an interview meeting to answer questions about the ways you might come in contact with arsenic and uranium. We will also review how to collect your water and urine specimens.

Watch this video to learn more about what happens during the participant interview meeting

What will I need to do?

Answer some survey questions, collect water from your faucet, and collect a urine specimen. All materials for collection and returning the specimens will be provided. Any information you share with us will remain confidential at all times.

What do I get in return?

Get your well water tested for FREEFree testing of your well water* and urine from the New Hampshire Public Health Laboratories. Your well water and urine will be tested for arsenic and uranium (common chemical contaminants to well water in NH). Your well water will also be tested for other chemicals, free of charge. We will refer you to someone who can help with interpreting results, should you need it.

*If you are unsure if you have a well, read through our fact sheet on wells Adobe Acrobat Reader Symbol,
Hoja Informativa Sobre Pozos Adobe Acrobat Reader Symbol (Spanish), to learn more. You most likely have a well if you do not receive a water bill from your city or town.

How do I sign up?

This is a targeted public health study, which means we are only working in a limited number of communities at this time. Currently, we are actively recruiting participants from the following towns: Farmington, Hampton Falls, Hudson, Milton, Newmarket, Peterborough, Seabrook, and Somersworth. We are also recruiting a small, comparison population from Concord in which only residents on public water will be included. Randomly selected households will receive a Recruitment Postcard Adobe Acrobat Reader Symbol, Tarjeta Postal Adobe Acrobat Reader Symbol (Spanish). If you have questions about the study or would like to find out if you are eligible to participate, please contact Amanda Cosser, Study Coordinator, or Melissa Levesque, Program Specialist (see contact information below). You may also begin the eligibility process online by completing our brief enrollment form on Survey Monkey, Formulario de inscripción de Survey Monkey (Spanish).

Please note: Enrollment has closed for the towns of Bow, Deerfield, Dunbarton, Goffstown, and Weare. You may still provide your contact information via the methods described above and we will reach out to you should recruitment reopen. Thank you for your interest.
